modal number = 47; range = 41 to 95. Fifty karyotypes showed no consistent loss or gain of particular chromosomes. Twenty-eight percent of the cells with 45 chromosomes were C-; 53% of all cells had an extra D and 35% had an extra F. Only N1 and N18 were not affected by gain or loss. No marker chromosomes noted.

The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.

Subculturing

Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 2 to 3 X 105 viable cells/mL. Maintain cell density between 2 to 3 X 105 and 1 to 2 X 106 viable cells/mL.

Medium Renewal: Add fresh medium (20% to 30% by volume) every 2 to 3 days

CCRF-CEM is a T lymphoblastoid cell line derived by G.E. Foley, et al. using cells obtained in November, 1964 from peripheral blood buffy coat of a 4-year-old Caucasian female with acute lymphoblastic leukemia.
